There was a good selection of apps to choose from this week. Leading the charge is Field Trip from Google’s Niantic Labs which can help you discover unusual and too-often-missed things close by. We’ve also got the lowdown on PassWallet (an Android take on Apple’s Passbook), a smart update to the New York Times, the prettiest accounting app you’ll ever see (Xero) and the official offering from Amtrak. Keep on track with our Android Apps of the Week.

Amtrak (Free)

Amtrak now offers an official Android app. It allows you to easily plan and book a trip on Amtrak trains and buses, check the arrival/departure time of trains, display your e-tickets, modify your reservations or search for station amenities and hours of operation. If you’re a regular customer, it’s easy to connect to your Amtrak Guest Rewards account, but even those who rarely ride Amtrak trains could find it useful when traveling across North America.
